Motor neurons don’t just move muscles. They may direct that motion too

Motor neurons don’t just move muscles. They may direct that motion too

A fruit fly study shows motor neurons do more than relay commands: They send signals back to the brain and organize movement sequences.

Motor neurons coordinate fruit fly feeding sequences through disinhibitory

A new study in Drosophila is challenging one of neuroscience’s most familiar ideas: that motor neurons are merely the final relay stations that carry commands from the brain to muscles. Instead, researchers report that these neurons can actively organize the precise order and timing of a behavior, creating a self-propagating neural sequence that coordinates feeding movements with millisecond accuracy. The discovery comes from simultaneous quadru…
